[BUG] When resuming a session, finished tries count towards new session tries - messing up ETA

[spaghetsie]

I left a session running for about 10 minutes during which ~9000 tries were done. Then I remebered to add -f option so I stopped the execution and resumed it using -R with the added option. Now after 1 minute I get:
[STATUS] 10166.00 tries/min, 10166 tries in 00:01h, 989834 to do in 01:38h, 32 active
even though the actual speed is somewhere around(from the previous session):
[STATUS] 634.00 tries/min, 634 tries in 00:01h, 999366 to do in 26:17h, 32 active

With time due to averaging it does converge towards the actual speed but I believe this is undesired.
